AU'roivroBIrE-JACK.

To all whom t may concern.' Y i v Be 1t known that I, FRANK ".R. PARMENTER,

a citizen of theUnlted States, residing atv Lansing, in the countyv of Ingham and State of Michigan, have invented a new andV useful .Automobile-Jack, of which the follow-y ing is a specification.

rl`he present invention relates to automobile jacks, and is particularly an improvement over' the automobile jack disclosed in my Patent' No. 1,196,392 granted August 29, 1916. v l s It is the/object of the invention to` provide a novel and'improv'ed device forautomatically lifting and supporting an automobile which is lrun ontothe same, so as to relieve the tires of the weight of the car.

The invention alsoA has for its object'the provision of a device o f the character'indicated improved generally in its construction and ydetails to enhance 4the utility and etliciency thereof. j 'v Vith the foregoing and vother objects in" view which will appear asthe description proceeds, the invention resides in thecombination vand arrangement of parts and inthe detailsof construction hereinafter described and claimed, it being understoodthat changes in the precise embodiment of the invention herein disclosed can be made within the scope of whatis claimed without departing from the spirit of the invention.

The invention is illustrat d in the accomy panying drawings, wherein Y Figure 1 is a plan View of the 'jack in prostrate position." j l Fig. 2 isa side elevation of the jackin said position.l l Fig. 3 is a longitudinal section-taken'on the line 3+?) of Fig. 1,'

the bars 2 and sills. Flat rails or 'boards 4 y yfor the wheels of the vehicle to run upon also rest flatly upon -the 'floor andl their inner vlongitudinally accord'inofto the wheel base of the automobile, said 'blocks 5 having'def pending flanges 5a at their sides to overlap the edges of the rails 4 and adapted to be secured thereto by holding` said blocks in their adjusted positions.

' Disposed above and parallel with'the sills 1 are lift' bars 6, .which may be constructed either of wood or of metal, the same' as thev 'sills 1. The bars 6 are mounted for upward and downward movement by means of links 7, 8 and 9 pivotally connecting said bars with the sills 1. The links `7 are adjacent to the rear Iends ofthe bars 6 at the inner sides of said bars and sills; the 'links 8 are immediately in front of thelinks 7 at the innerv and outer sides of the bars and sills; while the links '9 are at ,the forward "end of the structure at both the innerand outer sides ofthe bars 6 and sills 1. A lcasting 10 is fitted and secured upon the rear terminal ofv each sill 1, and' a transverse rodll extends through the said castings, -saidicastings being provided at their inner sides with lloopshaped bearings 12 through which the rod 11 extends, and the lower ends of the'links 7 are mounted upon the rod 11 within said bear-V ings 12. Ther lower ends of the links .8 are pivoted, as at 18, to the castings 10, and the lower ends of the links 9 are pivoted, as'at 14, to castings 15 fitted and secured upon the forward terminals of the sills 1. A transverse tie rod 16 is engaged through the castings 15 to assist in bracing the base, and a transverse tie bar or `brace 1a is also secured tothe sills 1 betweentheir ends. The up-y per ends of the links 8 are pivoted, as `at 17, to V.castings 18 fitted yand secured upon the rear terminals of the' lift bars 6, and the castingslS have loop-shaped bearings 19`-at their inner 'sides through which a transverse rod 2Oy extends, said 'rod also extending through the castings 18 themselves, and -the links 7 pivotally engaging the rod 2O within the bearings 19. The links? are slottedand have 'curved extensions `21 projecting above the bars' 6 and' curved rearwa'rdlyiV `The ends of the extensions 21 are connected by a ytransverse tie rod 22. The links y9 are v pivoted, as at 23, to castings 24 fitted and secured upon the forward terminals of the bars 6. The,castings 10, 15, 18 and 24 are Y usedlupon the ends ofthe wooden sills and lift bars, whereby to withstand the strains v to which the device is subjected'. -The castl Y and upwardly, thelinks l9 being swung willv move they blocks 26 forwardly andupwardly v or standards 28. .The ends of the castings ings or members 10,15, 18 and 24 are held in place upon .the sills and lift bars by the pivot bolts 1 and'` other parts extending therethrough.,

In order to raise and supportl the rear axlel or rear springs, the links 9 .extend upwardly above the pivots 23,'and the ends" of ,thee'x-y tensions 'arefpivoted, as at 25, to supporting members or blocks 26. Additional links27l l f are vpivotally connected with the. blocks or members 26 and castings 24, to assist the links 9 in moving the blocks 26 Vupwardly and downwardly as the lift bars 6 are moved likewise. jWhen the liftbars 6 are moved forwardly and downwardly, the blocks 26 aremoved` likewise relative to the lift' bars, and when the liftbars are moved forwardly relative-.to theY lift barsf6. e v n The rear sill-castings 10 have upstanding' brackets 4v28 through which a transverse rod orl'shaft 29 is engaged,iandfrollers. 30 are mountedAVV upon vsaid rod within the brackets 18 are curved, as at 81, to ride `over. ,the rollers as "the liftwbars. are raised land lowered. The castings 2,4 are provided with depending bracketsorhangers 82 throughV which 'a transverse rod orshaft32 is en-Vv gaged, androllers 33 are mounted uponV said `rod within the brackets to ride upon the curved ends 34 of the. castings 15 as the bars 6 are raised and lowered. The castings 15 and 18A have the'stops 35 projecting therefromV to Contact with'the rollerswhen the bars 6 areraised, to thereby limit the move'- `ment,l of saidbars.. i ,.Latches or catches 36 are pivoted, as at 37, within the slots of the-links 7 land project rearwardly, being ,provided between', their ends.` 'with downwardly opening notches 38 to engage the lrods-2,9 lwhen the bars 6 are in raised position, to thereby hold said bars y Y in said'position until the latches are released.

The rear free ends of the latches 86 are connected by a transverse .rod 39, to which Aa ropejor other flexible element can be connected forraisingthe latches from the seat of theautomobile, thus enablingfthe automobileto be lowered lwhile the operatory is seated, therein. vcoiled wire v retractileV spring A40 ,is terminally connected-with the j rods-` 1l` and 39 and tends to swing the latches 36j downwardly into engagement with the rod 29, so thatsaid latches will snap into engagement with-saidrod 29 when the lift bars 6 are raised.

Thev lift barsV 6 canfpbe connected 'by a transverse tie bar 41 between their ends to strengthen them.

The lift bars are provided with special means for supporting the front axle ofthev automobile. Thus, plates 42 are seated upon the castings 18 ofthelift bars and are provided with depending arms 43L overlapping said castings, whereby the' plate 42 'and its arms 'straddle said castings` The' arms48- carry set screws 44 whereby the plates j 42V can be yfirmly-held in place by tightening the set screws which bear againstthei cast-v l ings 18. A block 45 isseatable on each plate 42. and is provided with va 4depending por! tion V46 at one end toseat upon therespective casting 18 and bar 6 beyond either end of the plate 42, thek block 45' beingreversible to' occupylthe full lineposition as seen in' Fig. 2, or the dotted line positionj in said figure. That end 'of the' block45 having the lug 46 is inclined 'and cu'ryed, as at 47 and each block` 45`c'anjbe held rmly in place by means of'fa bolt48'engaged dowfn-r wardlytherethrough into thebar 6 orjcasting 158. The plates 42 have upstanding'lugs 49attheir lopposite side edges for` holding i f the blocks 45 therebetween-upon the plates 42. .Blocks 50 having vthe oppositejinclined faces yare seatable and adjustable -u'pon' the blocks 45fand have depending .lugs-'52V at opposite sides to overlap l and straddle` the sides of the. blocks-'45, and the blocks50` can be heldin variousadjusted positions by se e meaiisof bolts 53 extendingdownwardly d f front axle strikesfthe extensions 21hof'the links 7 and moves 'said extensions rear-` wardly dueto the momentum .ofthe automobile, thus swinging the links 7, and "mov-y ing the bars 6 rearwardly and vu'pwa'rdlytol rio automatically'jack up the automobile. jThe front axle can readily passfloverftheblocks 26, andv when'the bars 6 are raised, theblocks 26 are raised` from'the bars 6, and willjco'n` ltactfwith" andraise therear vaxle or'nrear springs properly which are generally spaced furtherV from theground than thefrontaxle.

Whenthe bars 1 6 'are raised, thelatche's'l36 in engaging" theV rod 29v hold them'in this lsol position, and the front axle is engaged and supported by the blocks 45. The blocks 50 can be so adjusted, that the front axle will, in resting upon the incline faces thereof when engaging the extensions 2l, shift forwardly slightly away from said extensions, in order that when the latches 36 are raised and the bars 6 moved forwardly and downwardly under the weight of the car, the front axle will be clear of the extensions 21. The blocks 50 are removable and adjustable, and the blocks 45 are removable and reversible, in order that their inclined ends i7 maybe brought into play with certain automobiles for accomplishing the same *resultsv as the incline faces 5l of the blocks 50.
